You have a power supply decaying; it will likely get worse. There may be board repair of this available so locate the power supply board - look at the assembly that seems closest to the AC cord, check the board number and search on it.
NOTE: There may be more than one number on the board since the bare board may have its own but it will be obviously a part of the board. The assembled board number will look much more temporary and may even be on a label.
If you locate a service company that claims the ability to service it, pick their brains a little since it may not be a main power supply failure but rather another, possibly separate board that produces the high voltage for the CRTs. If you do find a separate board that seems to be servicing the CRTs, note that board number too and ask them about both.

My Mitsubishi WT 46807 will not power up. The green light on the front stays on for approximately 2 seconds and then goes out with no audio or visual. I tried unplugging the set for about 15 minutes but...


yes!

When you turn set on and power light goes out do the self check this set has.

On front of set when light goes out press and hold both the Menu and Input (device) buttons at the same time and hold both for at least five seconds and then release both.

Power light will blink a two digit error code like 2 blinks,2 blinks, a pause and repeat it several times.


Let me know what error code you find and I will tell you what it means. Make a comment here and I will assist you.

Does the Mitsubishi WT-46807 need a converter box to receive a HD signal?


Yes, this model only has one HD input--it is the one marked on the back of the set as DTV---you need to hook a box for HD to that input.

Burnout ? wt-46807


There could be a Pip problem or the vertical sweep could have went out also so then the set shuts down the video so it does not burn a line across the tubes. Theres really no way to tell what is wrong or it would just be a guess, a shot in the dark. Call out an authorized repair depot and get an estimate. Good Luck
